The invention provides a satellite configuration and a switching method of a multi-band planar phased-array antenna, the satellite configuration comprises a satellite platform 1, a panel antenna group and a solar cell array 5, the panel antenna group comprises a plurality of panel antennas with different bands and all connected with a top plate of the satellite platform 1, and the solar cell array 5 is connected with a bottom plate of the satellite platform 1. The plurality of panel antennas with different frequency bands are folded and cling to the first side surface, and the solar cell array 5 is folded and cling to the second side surface; and in a flight state, the plurality of panel antennas with different frequency bands are all unfolded until the plurality of panel antennas with different frequency bands and the top plate of the satellite platform 1 are located on the same plane, and the solar cell array 5 is unfolded until the solar cell array 5 and the bottom plate of the satellite platform 1 are located on the same plane. The satellite configuration is stable in structure, can bear large-size and large-mass loads, and has very high adaptability to existing satellites adopting sun-synchronous orbits and low-dip-angle orbits for loading flat plate type effective loads.
本发明提供了一种多频段平面相控阵天线的卫星构型及切换方法,包括卫星平台1、平板天线组以及太阳电池阵5,平板天线组包括多块不同频段的平板天线且均连接卫星平台1的顶板,太阳电池阵5连接卫星平台1的底板,处于发射状态时,多块不同频段的平板天线均收拢且紧贴第一侧面,太阳电池阵5收拢且紧贴第二侧面;处于飞行状态时,多块不同频段的平板天线均展开,直至多块不同频段的平板天线与卫星平台1的顶板位于同一平面,太阳电池阵5展开,直至太阳电池阵5与卫星平台1的底板位于同一平面。本发明卫星构型的结构稳定、可承载大尺寸及大质量载荷,对于目前采用太阳同步轨道和低倾角轨道的装载平板式有效载荷的卫星具有很高的适应性。
